re:19VLTP22 vs 19VJPT22

In message "19VLTP22 vs 19VJPT22", you write:

>Does anyone know if the 19VJPT22 tube has a higher resolution (finer dot
>pitch) than the 19VLTP22 tube?

I don't think any of us is going to be able to comment but I'd
imaginge that the original manufacturer probabaly could still tell
you (and they're probably the only ones).

There is one more experiment to be made before this is advisable.
Yes, I transplanted a set of Wells-Gardner hardware onto an Amplifone
tube assembly BUT to do what you are suggesting would require that
somebody test the results of transplanting a Wells-Gardner yoke onto
an Amplifone tube. The yoke is what determines the pincushioning or
barreling and if you wanted to put an Amplifone tube into a Tempest,
you'd want to remove the Amplifone yoke and put on a W-G to get rid of
the barrelling that would otherwise be present. I have a spare,
working W-G yoke (NOS) that I would loan to somebody willing to do
this experiment but I have no plans on tesing this myself (but I am
90% sure it will work).
